Hi everyone, I'm working on a simple kernel module to get an idea of platform drivers and devices. I created a dtbo for my board (Beaglebone Black) and loaded it. When I install my kernel module with insmod I get an error from the pinmuxing driver. Here is the relevant dmesg output: [10971.691781] gpio_platform_drv: loading out-of-tree module taints kernel. [10971.699577] pinctrl-single 44e10800.pinmux: Invalid number of rows: 0 [10971.708571] pinctrl-single 44e10800.pinmux: no pins entries for gpio-irq-pin C code for the kernel module is at this link: https://hastebin.com/share/ejimanodir.cpp And the dtbo source is at this link: https://hastebin.com/share/xasizepicu.javascript I assume the issue is with the dtbo but I might be wrong. Any help might be appreciated. Thanks, Syed Kumail
